could i be pregnant?

for the past two months i have had an un-regular period. I usually get my period for 4-5 days. and for the past 2 months i have gotten then for a day in a half and after that i don't bleed but when i clean my self i have a very light pink kind of discharge. mood swings all the time. breast feel fuller, dizziness , lots of heart burn, after i eat i just have a feeling of having to vomit but i cant. and now i feel so horny all the time, all day every day for the past week. i had never been like that. i am 20 years old, i have taken a pregnancy test but its negative.
oh & i have a light line from my belly button going down ....

That line usually shows up as the tummy starts to grow. You should go see a doctor because they could do a blood test to see if you are pregnant. If you aren't, they could help you with the other stuff and symptoms you've been having, because it could be anything. Good luck.
